Recently, a piece of news about heart stents circulated on the Internet, "TV stations reported that the country will gradually stop the operation of heart stent installation. Instead, it will be promoted clinically: the treatment method of removing hard plaque in heart blood vessels with a polishing probe back and forth. The XX hospital has already started clinical application and will soon promote this treatment nationwide." A medical animation simulation video is also attached.
The above news was verified by Dr. Hou Xiaoping, Chief of Cardiovascular Medicine, and is not true. "This is actually an internal coronary artery grinding procedure, which is not a substitute for cardiac stenting. And the video attached to the news is actually a simulation video of intracavitary lithotripsy for urinary stones, which is a lithotripsy treatment for ureteral and renal pelvic stones, and cannot be used to discuss techniques related to cardiac stents.
Intracoronary spingrinding, which uses a spingrinding tip with diamond particles, is placed into the vessel to polish calcified or fibrotic plaque, modifying and opening the vascular channels so that guidewires, balloons, and stents can pass through areas of the vessel with moderate to severe calcified stenosis. The calcification of the vessel is spun off and easily expanded, and the fit between the placed stent and the vessel wall is improved, which increases the success rate of opening the vessel and placing the stent.
Coronary revolutions were developed in the 1980s and entered the clinic in the 1990s. Since the new century, its application in China has gradually increased and is now more common. It also has indications and risks, and depending on the condition, the spin mill technique can be combined with different techniques such as stent placement and balloon dilation. Each of these techniques has its own role to play, so it is not possible to talk about the replacement of cardiac stents by spin mill technology.
